Arabidopsis thaliana (Mouse-ear cress) At4g37470 KAI2 AtKAI2 HTL hyposensitive to light
orthologue to rice OsDLK1 paralogue to AtD14 DWARF14 || KARRIKIN INSENSITIVE2 (KAI2) karrikin receptor. Involved in seed germination and seedling development. Essential for plant responses to karrikins, a class of butenolide compounds, structurally similar to strigolactones, released from burning vegetation that stimulate seed germination and enhance seedling photomorphogenesis. KAI2 is not required for strigolactone-mediated responses, but MAX2 is necessary for responses to karrikins and strigolactones. Lacks detectable hydrolase activity against karrikin. Karrikin binding induces a conformational change. Mutations in KAI2, encoding the proposed karrikin receptor, result in hypersensitivity to water deprivation. HYPOSENSITIVE TO LIGHT or HTL. Mutant displayed a long hypocotyl phenotype under red, far-red, and blue light
